#Iranian Scientists Use Gas Sensor to Detect Hydrogen Iranian researchers designed a sensor with the capability of rapidly detecting the amount of hydrogen existing in the environment.
This sensor can detect the leak of hydrogen in hazardous environment which can prevent the explosion.
Hydrogen sensors are convertors that create electrical signal by adsorbing hydrogen molecules, which depends on the concentration of the hydrogen.
In this research, a capacitor MOS sensor was produced that detects the leak of hydrogen at explosive level (4 vol. percent) in less than two minutes.
Capacitor sensors detect any change in the environment through changing the electrical capacity of the capacitor.
The advantages of these sensors over other types of sensors are stability long lifetime and low response time.
For instance, this sensor can be used in the monitoring of hydrogen concentration during the production of ammonia, methanol and hydration of hydrocarbons.
Among other applications of this sensor, mention can be made of desulfurization of petroleum products, production of jet fuel and launching of aircrafts and other aerospace applications.
This research also studies the effect of the thickness of oxide layers in the sensor structure on its properties and performance.
the sensor detects hydrogen in a shorter period of time as the thickness of oxide layer decreases.
Response time has been calculated to be 84 seconds for a capacitor sensor with oxide layer thickness of 28 nanometers.
Results of the research have been published in Sensors and Actuators B: Chemical, vol. 216, issue 1, 2015, pp. 367-373 3

#Researchers Build a Transistor from a Molecule and A few Atoms A team of physicists from the Paul-Drude-Institut für Festkörperelektronik (PDI) and the Freie Universität Berlin (FUB), Germany, the NTT
and the U s. Naval Research Laboratory (NRL), United states, has used a scanning tunneling microscope to create a minute transistor consisting of a single molecule and a small number of atoms.
The observed transistor action is markedly different from the conventionally expected behavior and could be important for future device technologies as well as for fundamental studies of electron transport in molecular nanostructures.
Transistors have a channel region between two external contacts and an electrical gate electrode to modulate the current flow through the channel.
In atomic-scale transistors, this current is extremely sensitive to single electrons hopping via discrete energy levels.
Single-electron transport in molecular transistors has been studied previously using top-down approaches, such as lithography and break junctions.
But atomically precise control of the gate which is crucial to transistor action at the smallest size scales is not possible with these approaches.
The team used a highly stable scanning tunneling microscope (STM) to create a transistor consisting of a single organic molecule and positively charged metal atoms
positioning them with the STM tip on the surface of an indium arsenide (Inas) crystal. Kiyoshi Kanisawa, a physicist at NTT-BRL, used the growth technique of molecular beam epitaxy to prepare this surface.
Subsequently, the STM approach allowed the researchers, first, to assemble electrical gates from the+1 charged atoms with atomic precision and, then,
similar to the working principle of a quantum dot gated by an external electrode. In our case, the charged atoms nearby provide the electrostatic gate potential that regulates the electron flow
But there is a substantial difference between a conventional semiconductor quantum dot comprising typically hundreds or thousands of atoms and the present case of a surface-bound molecule:
and orientational dynamics of the molecule This simple and physically transparent model entirely reproduces the experimentally observed single-molecule transistor characteristics.
The perfection and reproducibility offered by these STM-generated transistors will enable the exploration of elementary processes involving current flow through single molecules at a fundamental level.
which they can lead will be important for integrating molecule-based devices with existing semiconductor technologies.

#An easy, scalable and direct method for synthesizing graphene in silicon microelectronics: Korean researchers grow 4-inch diameter, high-quality, multi-layer graphene on desired silicon substrates,
an important step for harnessing graphene in commercial silicon microelectronics Abstract: In the last decade, graphene has been studied intensively for its unique optical, mechanical, electrical and structural properties.
The one-atom-thick carbon sheets could revolutionize the way electronic devices are manufactured and lead to faster transistors, cheaper solar cells, new types of sensors and more efficient bioelectric sensory devices.
As a potential contact electrode and interconnection material, wafer-scale graphene could be an essential component in microelectronic circuits,
but most graphene fabrication methods are not compatible with silicon microelectronics, thus blocking graphene's leap from potential wonder material to actual profit-maker.
Now researchers from Korea University in Seoul, have developed an easy and microelectronics-compatible method to grow graphene
and have synthesized successfully wafer-scale (four inches in diameter), high-quality, multi-layer graphene on silicon substrates.
which ions are accelerated under an electrical field and smashed into a semiconductor. The impacting ions change the physical, chemical or electrical properties of the semiconductor.
In a paper published this week in the journal Applied Physics Letters, from AIP Publishing,
which takes graphene a step closer to commercial applications in silicon microelectronics.""For integrating graphene into advanced silicon microelectronics, large-area graphene free of wrinkles, tears and residues must be deposited on silicon wafers at low temperatures,
which cannot be achieved with conventional graphene synthesis techniques as they often require high temperatures, "said Jihyun Kim, the team leader and a professor in the Department of Chemical and Biological engineering at Korea University."
"Our work shows that the carbon ion implantation technique has great potential for the direct synthesis of wafer-scale graphene for integrated circuit technologies."
Graphene's unique optical, mechanical and electrical properties have lead to the one-atom-thick form of carbon being heralded as the next generation material for faster, smaller, cheaper and less power-hungry electronics."
"In silicon microelectronics, graphene is a potential contact electrode and an interconnection material linking semiconductor devices to form the desired electrical circuits,
the method is suited not for silicon microelectronics, as chemical vapor deposition would require a high growth temperature above 1,
"Thus, we are motivated to develop a transfer-free method to directly synthesize high quality, multilayer graphene in silicon microelectronics."

For example, recent LANP plasmonic research has led to breakthroughs in color-display technology, solar-powered steam production and color sensors that mimic the eye."
Today's most efficient photovoltaic cells use a combination of semiconductors that are made from rare and expensive elements like gallium and indium.
Halas said one way to lower manufacturing costs would be to incorporate high-efficiency light-gathering plasmonic nanostructures with low-cost semiconductors like metal oxides.
"The efficiency of semiconductor-based solar cells can never be extended in this way because of the inherent optical properties of the semiconductors."

Each consisted of a plasmonic gold nanowire atop a semiconducting layer of titanium dioxide. In the first setup, the gold sat directly on the semiconductor,
and in the second, a thin layer of pure titanium was placed between the gold and the titanium dioxide.
The first setup created a microelectronic structure called a Schottky barrier and allowed only hot electrons to pass from the gold to the semiconductor.
The second setup allowed all electrons to pass.""The experiment clearly showed that some electrons are hotter than others,
including medicine, electronics and energy. Discovered only 11 years ago, graphene is one of the strongest materials in the world, highly conductive, flexible, and transparent.
#Researchers boost wireless power transfer with magnetic field enhancement Wireless power transfer works by having a transmitter coil generate a magnetic field;
a receiver coil then draws energy from that magnetic field. One of the major roadblocks for development of marketable wireless power transfer technologies is achieving high efficiency."
By placing the MRFE between the transmitter and the receiver (without touching either) as an intermediate material,
"We realized that any enhancement needs to not only increase the magnetic field the receiver'sees, 'but also not siphon off any of the power being put out by the transmitter,
"Ricketts says.""The MRFE amplifies the magnetic field while removing very little power from the system."

robots and exoskeletons having great reach; morphing aircraft; giant-range strain sensors; failure-free pacemaker leads;
and super-stretchy charger cords for electronic devices. In a study published in the July 24 issue of the journal Science,
the scientists describe how they constructed the fibers by wrapping lighter-than-air, electrically conductive sheets of tiny carbon nanotubes to form a jellyroll-like sheath around a long rubber core.
the researchers made strain sensors and artificial muscles in which the buckled nanotube sheaths serve as electrodes
and the thin rubber layer is a dielectric, resulting in a fiber capacitor. These fiber capacitors exhibited a capacitance change of 860 percent
when the fiber was stretched 950 percent.""No presently available material-based strain sensor can operate over nearly as large a strain range,
